MTN giants think they can treat customers like they doing us a favour

I got a call from Thubelihle NkomoC: +***9 from the Clear water branch saying that I am due for an upgrade and that the Zphone was now available for me. She was very quick to upgrade and now she ignores me. I upgraded beginnig August and to date I still dont have a smart watch. Apparently I must contact samsung for the watch. Why should I as I had a contract with MTN not samsung . I even went in store to the store manager and he promised he will come back to me , but assured me this will be resolved soonest. I also got acall from a lady saying that she understands my frustration .. but still 3 months later nothing.
